IMPROVEMENT m DANCING TOYS.

Specification forming part of Letters Patent No. 17 ,216, dated December21, 1875; application filed October 30, 1875.

To all whom it may concern I Be it known that I, BENJAMIN 1). DE FOR-EST, of Mount Vernon, in the county of Westch ester and State of NewYork, have invented certain new and useful Improvements in Dancing Toys;and I do hereby declare. that the following is a full. clear, and exactdescription thereof, which will enable others skilled in the art towhich it appertains to make and use the same, reference being had to theaccompanying drawings, and to the lettersof reference marked thereon,which form a part of this specification.

Figure 1 is a plan View of my improved dancing toy, showing the floor ortable removed; Fig. 2, a side elevation, showing the side of the boxinclosing the battery removed; Fig. 3, a view of wire frame forsupporting the toy or toys.

Like letters in all the figures of the drawing indicate like parts.

This invention consists of a dancing toy operated by means of a galvanicbattery and electro-magnet, combined with a floor or table for the toytovibrate or (lance upon, so as to permit the vibrating or dancing vmovement imparted to the toy to be continued for an indefinite time, oras long as desiredfwhich cannot be done with the clock machinerynow usedfor that purpose, as the spring requires to be Wound up to keep themachine going, and, besides, the occasional breaking of the with a stem,b, by which it is attached by a pivot to the outer end of the lever orarm C, connected withthe battery located in box D. The table or floor E,which rests upon the box, is provided with guide holes or slots 00,through which the arms a a, pass and vibrate. On this table the toys areoperated, or made to dance, by the'vibrating movement of the leverproduced by an electrical current from the battery, in the usual manner.

Any galvanic battery and electro-magnet will answer for the purposewhich has the usualvibrating lever and armature, but for cheapness.simplicity, and safety, the common blue-stone battery is preferable.

A regulating-shaft, F, having a thumb-screw, d, on the end of it, isplaced across the box, and connected with the lever by a spiral spring,d, so as to provide a tension upon the'lever, by which its movement canbe stopped, diminished, or increased, as may be desired.

By increasing or diminishing the tension of the lever-spring, a greateror less vibration may be given accordingly, or the tension may be so farincreased as to cause a cessation of the vibration altogether, whenpreferred.

Having thus fully described my invention, what I claim therein as new,and desire to secure by Letters Patent, is-

1. A dancing toy, operated by means of an electro-magnet, combined witha table or floor for the toy to vibrate or dance upon, substantially asdescribed.

2. The combination of a wire-frame, having one or more upright arms, a,and provided with stem 1), with vibrating-"lever G of an electro-magnet,and table E, having one or more guide-holes, c, substantially asdescribed.
